Calibration of the model parameters in the navigation devices on the basis of fiber-optic gyroscopes

Features of navigation devices based on fiber-optic gyroscopes cause problems in their practical application and require calibration before use. Algorithms of accumulation and processing of information of strapdown inertial blocks on the basis of fiber-optic gyroscopes and blocks of determination of coordinates of stars are given. The calibration algorithms are modified to decrease on-Board computer memory and take into account the time limitations of the program execution. The results of modeling proved the effectiveness of the proposed solutions.
